Updates for Firefox 133 beta

[Elchi3]

The @openwebdocs BCD collector project v10.12.5 found new features shipping in Firefox 133 beta which was released today. Currently, the collector covers about 90% of BCD, so the following list might not be exhaustive. Also, if a feature is in Firefox Nightly only, it is not considered here.

With this PR, BCD considers the following 29 features as shipping in Firefox 133:

• api.ImageDecoder
• api.ImageDecoder.ImageDecoder
• api.ImageDecoder.close
• api.ImageDecoder.complete
• api.ImageDecoder.completed
• api.ImageDecoder.decode
